RHEL8_Linux下载ansible

本章内容主要介绍RHEL8中如何安装ansible?

• ansible时如何工作的
• 在RHEL8中安装ansible

1.ansible工作原理? ? ? ??

1）ansible是通过ssh连接到被管理主机，然后执行相关操作的，如图

2.安装ansible

1)先安装系统的开发工具

[root@node01 ~]# yum -y groupinstall 开发工具

2) 挂载镜像

[root@node01 ~]# mount /dev/cdrom /mnt/
mount: /mnt: /dev/sr0 already mounted on /var/ftp/dvd.
[root@node01 ~]# 

[root@node01 ~]# cat /etc/yum.repos.d/aa.repo 
[aa]
name=aa
baseurl=file:///mnt/AppStream
enabled=1
gpgcheck=0

[bb]
name=bb
baseurl=///mnt/BaseOS
enabled=1
gpgcheck=0
[root@node01 ~]# 

[root@node01 ~]# yum -y install https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm
[root@node01 ~]#  sed -i 's|^#baseurl=https://download.fedoraproject.org/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*
[root@node01 ~]#  sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*

5）下载Python3.12.1

[root@node01 ~]# wget https://www.python.org/ftp/python/3.12.1/Python-3.12.1.tgz
[root@node01 ~]# tar -zxvf Python-3.12.1.tgz 

6）安装必须的包

[root@node01 ~]# dnf -y install gcc zlib* libffi-devel

7）安装Python

[root@node01 Python-3.12.1]# cd Python-3.12.1/
[root@node01 Python-3.12.1]# ./configure --prefix=/usr/local/python3 --enable-optimizations
[root@node01 Python-3.12.1]# make
[root@node01 Python-3.12.1]# make install

8）删除远程的Python3和pip3

[root@node01 Python-3.12.1]# rm -rf /usr/bin/python3
[root@node01 Python-3.12.1]# ln -s /usr/local/python3/bin/python3 /usr/bin/python3
[root@node01 Python-3.12.1]# rm -rf /usr/bin/pip3
[root@node01 Python-3.12.1]# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

9）查看Python3和Pip3是否正确的被安装

[root@node01 ~]# python3 --version
Python 3.12.1
[root@node01 ~]# pip3 --version
pip 23.2.1 from /usr/local/python3/lib/python3.12/site-packages/pip (python 3.12)
[root@node01 ~]# 

3.正式安装ansible

[root@node01 ~]# rpm -ivh ansible-2.9.11-1.el8ae.noarch.rpm 
错误：依赖检测失败：
	python3-cryptography 被 ansible-2.9.11-1.el8ae.noarch 需要
	python3-jinja2 被 ansible-2.9.11-1.el8ae.noarch 需要
	sshpass 被 ansible-2.9.11-1.el8ae.noarch 需要
[root@node01 ~]# 

1）安装依赖

[root@node01 ~]# yum -y install python3-cryptography
[root@node01 ~]# yum -y install python3-jinja2
[root@node01 ~]# rpm -ivh sshpass-1.06-3.el8ae.x86_64.rpm 

2）再次安装ansible

[root@node01 ~]# rpm -ivh ansible-2.9.11-1.el8ae.noarch.rpm

   1:ansible-2.9.11-1.el8ae           ################################# [100%]
[root@node01 ~]# 

3）使用命令检查ansible的安装结果

[root@node01 ~]# ansible --version
ansible 2.9.11
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.6/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.6.8 (default, Sep  9 2021, 07:49:02) [GCC 8.5.0 20210514 (Red Hat 8.5.0-3)]
[root@node01 ~]# pip3 --version
pip 23.2.1 from /usr/local/python3/lib/python3.12/site-packages/pip (python 3.12)
[root@node01 ~]# 

[root@node01 ~]# cat /etc/hosts | grep node
